I am running Windows 2008 R2 Standard, with Exchange 2010.
I have a conference room calendar that is shared with all my co-workers in the office.
A sub-tenant who moved in yesterday, and has his own Exchange Server. He wants to be able to access my conference room calendar, and add/change/delete for items that pertain to him.
Is it possible to share a calendar with him? Can I set "permissions" to create/modify/delete items that only pertain to him?
